HANGER.

Application filed March 13, 1922. Serial No. 543,248.

York. in the county of New York and State,

of New York, have invented certain ynew and useful Improvements in Hangers, of which the following is a speciiication.

This invention relates to'hangers adapted particularly for fastening structural iron work to the sides of a building wall, such as fire escape brackets etc.

The invent-ion has for its objects the provision of a device of this character which is simple in construction. durable and inerpensive; which is adaptable for attachment to a buildingr wall without necessity of employing rivets or riveting machines; which, when fixed in place, maintains secure connection with the structure to which it is attached; Aand which is readily attachable and detachable by means of ordinary tools, as a screw driver and wrench and which is adapted to be expanded within'a wall .recess before the bolt for hanging an auxiliary structure is inserted.

In carrying out my invention I employ elongated segmental elements, conical expanders for spreading said segmental elements against a cylindrical aperture formed 8@ in a building wall, screw means for actuating the eXpanders and other novel features hereinafter'fully described and specifically set forth in the appended claims.

In the accompanying drawings forming part, of this specification, Figure 1 is a side view illustrating one example of my iinproved hanger;

Fig. 2 is a front end View thereof;

Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 1;

Fig. 4 is a side View illustrating one example of a bolt and spreader element employed in the assemblage of my improved device;

Fig. 5`is a fragmentary sectional view of a part of the device;

Fig. 6 is a side view showing a slightly modified form of the device; and

Fig. 7 is a longitudinal sectional view taken on the line 7 7 of Fig. 6.

In the drawings, referring particularly to Figures 1 to 3, 1 indicates a disc or head adapted to be countersunk in a shallow recess 2 formed around the inlet of a cylindrical recess 3 of a building wall 4;, said recess may constitute a hole extended entirely through a' shallow wall, as shown by full lines Fig. 3 of the drawings, or the recess may extend only partly through the wall. as shown by dotted lines la.

The head 1 has a central" bore 1.?, and

formed through said head 1, on a diametrical i line and located at equal distances from the center of said head are .two-oaenino's 5 v through which the contracted ends 6 of the elongated segments, or clamping elements 6 are extended', these contracted ends of the segments are respectively provided with la laterally turned flange 7 whichextends obhquely towards the head '1, when the segments are extended parallel with each other',

as shown in Fig. 5 of the drawings,- whereby when said clamping elements are spread or fully expanded, as shown in Fig. 3 of the drawings, the inner surfaces of the flanges` are in alignment with the face of the head 1, whereby a closed oint is maintained to prevent rain or snow from entering through the opening 5. n

The spreading element comprises a conica-l plug S Ahaving oppositely located lugs 9 through which screws 10 are threaded, saidv 1 screws `respectively Vprovided with a conical head 10a, whichbears against a conical part 11a of a cylindrical recess 11.. The spreading element is further provided with an interiorly screw-threaded bore 12 Yfor engaging a screw-bolt 13 having a squared head 14, whereby the bolt 13 may be turned` to coincidentally actuate thev spreader 3 and@ clamp a bracket member. or. other device 15 to the outer face of the wall 4L. Instead of screwing the bolt 13 into the spreader 8, said spreader may be provided with a squared recessSa for engaging the bolt head 141, and said bolt may be 'fastened by means of a nut 16, as shown by Fig. 4 of the drawings.

In the modificationv illustrated by Figures 6 and 7 of the drawings, I provide two conical spreaders 17, 17 a having respectively lugs 18, 18a, said spreaders being connected by adjusting screws 19 which rotate through the lugs 18a and arethreaded through interior screw threaded openings of the lugs 18, the segments, or clamping members being held on the spreaders by means of a resilient split ring 21 which engages grooves 22 of the clamping members, the spreader 17 having a screw threaded bore 23 for engaging a bolt 13, and the spreader 17aL having a smooth bore 24: through which said bolt may rotate.

. panded and nel', indicated by l5, (sce Fig. 3 oi' the drawings)r and turned in the threaded spreader nntil the-segments are further extheel ement l5 vis ti ghtly clamped into ,fixed relation .with the building wall,

" the recesses ll' of the plate 'l, when such plate is used, admitting of slight forward movement ot'. the heads of the adjusting screws. v

lWhile l have illustrated and described fair exam les of mv im Aroved hanger l do not P o v ters Patent, is

conline myself to the specific details oit mere mechanical constructions shown, as under the spirit oi my invention l believe that l am entitled to employ such variations oi minor detail as may fall within the scope of the appended claims.

Having thus described my invention, what l claim as new and desire to secure by Letl. ln a hanger for fixing auxiliary structural work to the tace of a building wall, a slidably adjustable conical spreader having` a radial lug, and a clamping element for engaging a recess in the wall, means engaging 'V said lug for adjusting said spreader whereby the clamping element is actuated, anda bolt for expanding the clamping element.

2. ln a device for fixing auxiliary structural work to the face of a structure, a slidably adjustable conical spreader, segments constituting clamping elementsv which are in peripheral engagement with said spreader, screws yfor adjusting said' spreader, and means for holding the clamping elements in laterally adjustable relation with eachother.

3. ln a hanger :tor fixing auxiliary structural work to the .i'ace Oia structure, a slidably adjustable conical spreader, segments constituting clamping elements which are in peripheral engagement with said spreader, sciews.-or adjusting said spreader to morey the clamping elements for fastening the device within a recess of the structure, and meansltor further moving the clamping velements and coincidentally secure the auxln a device for fixing auxiliary structural -work to a structure, afslida-bly adjustable conica-i spreader having lugs for preventing rotation oi't' said spreader in a wall recess, segments constituting clamping elements which are in peripheral engagement with said spreader, and a screw for adjusting said spreader to expand the clamping elements with the wall recess', and a bolt for further expanding the clamping elements.

6. ln a hanger for ixing auxiliary structural work to the face of a building wall, a pair of slidably adjustable conical spreade-rs having, respectively, radially extending lugs, segments constituting clamping elements which are in peripheral engagement with said spreaders, screws engaging said lugs for primarily adjusting said spreaders to expand the clamping elements within building wall recess, and a bolt for further expanding said clamping elements. v
